I had the pleasure of researching global warming in my environmental science. I had always wondered about the actual facts behind the concept. I learned that global warming is a very natural process. The climate changes on our planet, over long periods of time. The controversy is whether or not human presence on Earth is accelerating the process. The answer is currently only speculation, but I tend to think that humans do accelerate the process. As I stated in my final paper, to assume that human beings can live on Earth and not have any affect on its environment is folly.
